Debugging A Network

Help! I’m trying to set up my first network and have jumbled something…

I have established and assigned my new subdomain with my host. I installed a new WP installation for the subdomain. It worked, great. Then I tried to get into my primary domain at: way2savenow.com/wp-admin
and now cannot get back into WP for that domain nor see the page without the log in instruction. My error reads:

No site defined on this host. If you are the owner of this site, please check Debugging a WordPress Network for help.

It says it is not defined on the host. How can that be? Did I direct something someplace I shouldn’t have?
